The gardens earn their CPMs on certainty about who is on the other end. You already have that certainty in your logins and subscriber file. Move it onto the Mastergraph, lift the match rate on every file that comes in, and validate the accuracy buyers are actually paying for.
Identity 1.0 outsourced the problem. Identity 2.0 hit the single-source ceiling and spent its time refereeing disputes between providers. Identity 3.0 is declared identity, independently validated at every connection.
Resolving your authenticated audience against the Mastergraph puts it on 302M validated Person IDs and 129M households, built by cross-checking 24+ providers against each other rather than taking one vendor’s word for it.
It runs on declared PII only. Email, phone, name and postal. No cookie, MAID, IP or CTV ID sits in the chain to deprecate or drift, so the identity infrastructure you stand up this year survives the next identifier that dies.
THE CASE FOR IDENTITY 3.0 →Every advertiser file that arrives for a direct deal gets matched against your audience, and the number that comes back decides how much of the campaign you can actually sell. Status-quo matching finds the one email string the advertiser happened to collect, or nothing.
ID Max resolves each record to the person, returns every validated ID that person uses, then extends to the household. Incoming files match at 40–200% higher validated rates, which is addressable inventory you already owned and could not reach.

Authenticated inventory already clears at a premium.
Grading is what converts that from a story into a rate card. Every linkage in your audience carries a Data Ratings tier (AAA–B) scored against Validation Sets of deterministic ground truth covering 1.4M US consumers. Buyers see the tier distribution before they bid.
